Brief Description: Contersinking Main Spar Flanges
I restarted work on the contersinking the mair spars. I was able to complete the upper flange on the right wing. But did not countersink the flush rivet positions underneath where the tank attaches to the flange. I still have a lot of countersinking left to do. I kept a test sample of aluminum dimpled with #40 dimple and all of my test spots are looking good. Proud, but not underdimpled.
